 must be provided using a separate voltage source and not be connected to V

CC

. The voltage 

specification requirements are defined in the middle of the VTT pinfield at the processor socket vias on the 

bottom side of the baseboard. The voltage specifications are measured with a 20-MHz bandwidth 

oscilloscope, 1.5 pF maximum probe capacitance, and 1 M minimum impedance. The maximum length of 

ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled 

into the oscilloscope probe.

 must be provided using a separate voltage source and not be connected to V

CC

. The voltage 

specification requirements are defined across VTT_SENSE and VSS_SENSE_VTT lands at the processor 

socket vias on the bottom side of the baseboard. The requirements across the SENSE signals account for 

voltage drops and impedances across the baseboard vias, socket, and processor package up to the 

processor Si. The voltage specifications are measured with a 20-MHz bandwidth oscilloscope, 1.5 pF 

maximum probe capacitance, and 1 M minimum impedance. The maximum length of ground wire on the 

probe should be less than 5 mm. Ensure external noise from the system is not coupled into the oscilloscope 

probe.
